ScienceDaily — Using productive farmland to grow crops for food instead of fuel is more energy efficient, Michigan State University scientists concluded, after analyzing 17 years' worth of data to help settle the food versus fuel debate.
"It's 36 percent more efficient to grow grain for food than for fuel," said Ilya Gelfand, an MSU postdoctoral researcher and lead author of the study.
"The ideal is to grow corn for food, then leave half the leftover stalks and leaves on the field for soil conservation and produce cellulosic ethanol with the other half."
